Abstract
Description
Technical Field
[0001] This application relates to the field of wood trim splicing technology, and more particularly to a splicing device for automotive wood trim. Background Technology
[0002] In automotive interior manufacturing, wood trim enhances the overall luxury of a vehicle with its natural texture. The nail gun splicing equipment uses pneumatic or electric drive to quickly drive special wooden nails into the splicing area to achieve mechanical fastening of the wood trim. This process ensures initial strength of the connection, is compatible with wood of different thicknesses, and facilitates later disassembly and maintenance. It is widely used in the mass production of automotive interiors.
[0003] However, existing automotive wood trim splicing equipment has the following drawbacks: for example, when nailing with a nail gun, existing wood trim splicing equipment often uses manual clamps on one or both sides, which can easily lead to uneven stress, resulting in warping of the boards or inconsistent width of the splicing seams. Utility Model Content
[0004] The purpose of this application is to enable the four clamping parts to move synchronously, so that the four sides of the combined wood veneer are evenly stressed, avoiding the warping of the board or the uneven width of the splicing seams caused by uneven stress.
[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: An operating table is included, a worm gear is movably mounted on the lower surface of the operating table, four inclined grooves are formed on the lower surface of the worm gear, a movable pin is provided inside the inclined groove, a limit pin is fixedly connected to the upper surface of the movable pin, a clamping member is fixedly connected to the upper surface of the limit pin, a connecting plate is fixedly connected to the lower surface of the operating table, a worm is movably mounted on the side wall of the connecting plate, a throttle is fixedly connected to the side wall of the worm away from the connecting plate, the worm meshes with the worm gear, and a nail gun is provided above the operating table.
[0006] As a preferred embodiment, the upper surface of the operating table is provided with four limiting grooves, the limiting pin is located inside the limiting groove, the outer surface of the worm gear is fitted with a support block, the lower surface of the operating table is fixedly connected to the support block, the lower surface of the movable pin is fixedly connected to a limiting plate, the limiting plate is located below the worm gear, and the side wall of the clamping member is fixedly connected to a buffer pad.
[0007] As another preferred embodiment, the upper surface of the operating table is fixedly connected with four fixing columns.
[0008] In a further preferred embodiment, a first motor is fixedly connected to the side wall of the fixed column at the left rear end, a first lead screw is fixedly connected to the output end of the first motor, and a movable frame is threadedly connected to the outer surface of the first lead screw.
[0009] As a preferred embodiment, a sliding rod is fixedly connected between the front fixed columns, and a movable frame is fitted onto the outer surface of the sliding rod.
[0010] As another preferred embodiment, a second motor is fixedly connected to the side wall of the movable frame, a second lead screw is fixedly connected to the output end of the second motor, and a movable block is threadedly connected to the outer surface of the second lead screw.
[0011] In a further preferred embodiment, a hydraulic cylinder is fixedly connected to the lower surface of the movable block, a movable rod is fixedly connected to the extended end of the hydraulic cylinder, and a nail gun is fixedly connected to the lower surface of the movable rod.
[0012] As a preferred embodiment, the lower surface of the operating table is fixedly connected with four legs.
[0013] Compared with the prior art, the beneficial effects of this application are as follows:
[0014] (1) Compared with the prior art, the splicing equipment for automotive wood trim uses a throttle, worm gear, worm wheel, moving pin, inclined groove, limiting pin and clamping parts. Before splicing the wood trim, it is necessary to limit and clamp the wood trim to facilitate the splicing work. Therefore, turning the throttle drives the worm gear to rotate, which in turn controls the rotation of the worm wheel. Since the moving pin is located inside the inclined groove, it can drive the four moving pins to move closer or further away from each other. When the four moving pins move closer to each other, they can drive the four limiting pins to move closer to each other, which in turn drives the four clamping parts to move closer to each other to limit and clamp the wood trim, preventing the wood trim from shifting during splicing. Compared with the existing splicing equipment, which often uses single-sided or double-sided manual clamps, uneven force can easily lead to warping of the board or uneven splicing seam width. The splicing equipment for automotive wood trim can allow the four clamping parts to move synchronously, so that the four sides of the combined wood trim are evenly stressed, avoiding the warping of the board or uneven splicing seam width caused by uneven force.
[0015] (2) Compared with the prior art, the splicing equipment for automotive wood trim uses a first motor, a first lead screw, a moving frame, a hydraulic cylinder, a moving rod, a nail gun, a second motor, a second lead screw, a moving block, and an operating table. The first motor can drive the first lead screw to rotate, which in turn drives the moving frame to move left and right, which in turn drives the hydraulic cylinder, the moving rod, and the nail gun to move left and right. The second motor can drive the second lead screw to rotate, which in turn drives the moving block to move back and forth, which in turn drives the hydraulic cylinder, the moving rod, and the nail gun to move back and forth. Therefore, the nail gun can be flexibly adjusted above the operating table. After the position is adjusted, the hydraulic cylinder drives the moving rod to move down, which in turn drives the nail gun to move down, so that the nail gun reaches the position where it needs to be nailed. The nail gun then nails and splices the wood trim. Attached Figure Description

[0021] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0022] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0023] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.
[0024] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.
[0025] like Figures 1-4 The illustrated assembly equipment for automotive wood trim includes an operating table 1. A worm gear 2 is movably mounted on the lower surface of the operating table 1. Four inclined grooves 3 are formed on the lower surface of the worm gear 2. A movable pin 4 is disposed inside each inclined groove 3. A limit pin 5 is fixedly connected to the upper surface of the movable pin 4. A clamping member 6 is fixedly connected to the upper surface of the limit pin 5. A connecting plate 7 is fixedly connected to the lower surface of the operating table 1. A worm gear 8 is movably mounted on the side wall of the connecting plate 7. The worm gear 8 is fixed away from the side wall of the connecting plate 7. A throttle 9 is fixedly connected to the worm gear 8, which meshes with the worm wheel 2. A nail gun 22 is installed above the operating table. This equipment is usually only used for splicing wood veneer pieces of fixed specifications. Before splicing the wood veneer, it is necessary to limit and clamp the wood veneer to facilitate the splicing work. Therefore, turning the throttle 9 drives the worm gear 8 to rotate, which in turn controls the rotation of the worm wheel 2. Since the moving pins 4 are located inside the inclined groove 3, they can be moved closer or further apart. When the four moving pins 4 are close together, they can drive the four limiting pins 5 to move closer together, which in turn drives the four clamping parts 6 to move closer together to limit and clamp the wood veneer, preventing the wood veneer from shifting during splicing. Conversely, controlling the four moving pins 4 to move further apart cancels the limiting and clamping state. The upper surface of the operating table 1 has a limiting groove 10. The limiting groove 10, together with the limiting pins 5, can limit the movement of the limiting pins 5, preventing the limiting pins 5 from rotating during movement, which in turn prevents the clamping parts 6 from rotating during movement. There are four limiting grooves 10. Pin 5 is located inside the limiting groove 10. A support block 11 is sleeved on the outer surface of the worm gear 8. The support block 11 can support the worm gear 8. The support block 11 is fixedly connected to the lower surface of the operating table 1. The limiting plate 12 is fixedly connected to the lower surface of the moving pin 4. The limiting plate 12 can prevent the moving pin 4 from moving upward. The limiting plate 12 is located below the worm gear plate 2. A buffer pad 25 is fixedly connected to the side wall of the clamping part 6. The buffer pad 25 can prevent the clamping part 6 from directly contacting the wood trim and causing damage to the wood trim.
[0026] Four fixed posts 13 are fixedly connected to the upper surface of the operating table 1. A first motor 14 is fixedly connected to the side wall of the left rear fixed post 13. A first lead screw 15 is fixedly connected to the output end of the first motor 14. A movable frame 16 is threaded onto the outer surface of the first lead screw 15. When the first motor 14 is working, it can drive the first lead screw 15 to rotate, thereby driving the movable frame 16 to move left and right, which in turn can drive the hydraulic cylinder 20, the movable rod 21, and the nail gun 22 to move left and right. When the second motor 17 is working, it can drive the second lead screw 18 to rotate, thereby driving the movable block 19 to move back and forth, which in turn can drive the hydraulic cylinder 20, the movable rod 21, and the nail gun 22 to move back and forth. Therefore, the nail gun 22 can be flexibly adjusted above the operating table 1. After the position is adjusted, the hydraulic cylinder 20 works to drive the moving rod 21 to move down, which in turn drives the nail gun 22 to move down, so that the nail gun 22 reaches the position where it needs to be nailed. The nail gun 22 works to nail and splice the wood veneer. A sliding rod 23 is fixedly connected between the front fixed columns 13. The sliding rod 23 can restrict the movement of the moving frame 16. The moving frame 16 is fitted on the outer surface of the sliding rod 23. A second motor 17 is fixedly connected to the side wall of the moving frame 16. A second lead screw 18 is fixedly connected to the output end of the second motor 17. A moving block 19 is threadedly connected to the outer surface of the second lead screw 18. A hydraulic cylinder 20 is fixedly connected to the lower surface of the moving block 19. A moving rod 21 is fixedly connected to the extended end of the hydraulic cylinder 20. The nail gun 22 is fixedly connected to the lower surface of the moving rod 21.
[0027] The lower surface of the control panel 1 is fixedly connected with four legs 24, which can support the control panel 1.
[0028] Working principle: Before splicing wood veneer panels, the panels need to be clamped to facilitate the splicing process. Therefore, turning the handle 9 drives the worm gear 8 to rotate, which in turn controls the rotation of the worm wheel 2. Since the moving pins 4 are located inside the inclined groove 3, they can move closer or further apart. When the four moving pins 4 move closer, they can move the four limiting pins 5 closer together, which in turn moves the four clamping parts 6 closer together to clamp the wood veneer, preventing it from shifting during splicing. Conversely, controlling the four moving pins 4 to move further apart cancels the clamping state. The first motor 14 then drives the first... The lead screw 15 rotates, which in turn drives the moving frame 16 to move left and right, which in turn drives the hydraulic cylinder 20, the moving rod 21, and the nail gun 22 to move left and right. The second motor 17 works, which drives the second lead screw 18 to rotate, which in turn drives the moving block 19 to move back and forth, which in turn drives the hydraulic cylinder 20, the moving rod 21, and the nail gun 22 to move back and forth. Therefore, the position of the nail gun 22 can be flexibly adjusted above the operating table 1. After the position is adjusted, the hydraulic cylinder 20 works, which drives the moving rod 21 to move down, which in turn drives the nail gun 22 to move down, so that the nail gun 22 reaches the position where it needs to be nailed. The nail gun 22 works to nail and splice the wood veneer.
